Firstly you can download the 3.0 beta here (you'll need your fusesource login) or the update site is here. If you'd rather stick with the stable GA version get it from the download page
Does it have eclipse plugin? Can I get the same features using eclipse plugin?Yes; use the update site to install the eclipse plugins for Fuse IDE into your eclipse; please use Indigo (3.7.x) and it works OK in JBoss 5.0.0.GA or vanilla eclipse java / jee. Doesn't yet support Juno though. Its easier to download the full RCP release though :)
what is the difference between fuseide and redhat developer?Fuse IDE was developed by FuseSource before the acquisition by Red Hat; so we'll be integrating them together into the Red Hat developer tools (JBoss Tools etc). Luckily there's a great fit between them with little overlap really! :)
Does Fuse support monitoring and managing message flow when services running in Cluster (say JBoss AS 7.x cluster)Yes, any JVM which has a fairly recent Camel inside should work fine provided you can connect to it over JMX. The message tracing is only supported so far in the Fuse distribution of Camel (it should be back ported to the Apache distro soon). The newer the Camel version the better! :)
Is the source for the examples downloadable from anywhere to have a play with?Yes. The easiest thing is to create the project inside Fuse IDE (New -> Fuse Project -> ...) and all the source code is included in the generated project; then you can just play immediately.
Where this code comes from to get included inside Fuse IDE is all over the place :) Mostly either the Apache Camel project's archetypes or the Fuse projects examples - so its easier to create the various projects and look inside the generated source.
Nice! Current state of JBoss integration? When do I get to use all these goodies -- Eclipse/JBossTools w SwitchYard (esp SCA editor) and Fuse (esp Camel EIP editor) together -- + your runtime tooling on JBAS7.1 / CDI / SwitchYard deployments?You should be able to use JBoss tooling and Fuse IDE together right now; unfortunately Fuse IDE isn't yet compatible with the SwitchYard SCA tooling (due to Graphiti dependencies); which hopefully we can fix soon - but Fuse IDE works with JBoss Tools and already includes the Drools / jBPM tooling too.
You should be able to use Fuse IDE today with JBoss Tools and AS 7.1; the more recent Camel version the better :). As an aside, the next Camel release should have awesome CDI support!
Please comment on using IDE (JMX explorer) in a QA fabric.So the Fuse Fabric tooling in Fuse IDE is really intended for developers; though you could have a Fuse Fabric for development, testing, QA, load testing, performance testing, user acceptance testing or production etc. So long as you don't mind developers tinkering with endpoints & routes; using developer tooling in QA is OK :)
Though Fuse Management Console is really intended for more locked down operation based environments; Fuse IDE is focussed on developers really.
What is roadmap for ide with merger?
Does Fuse support monitoring and managing message flow when services running in Cluster (say JBoss AS 7.x cluster)
Update: I should have mentioned if you want to use the beta, which uses the Early Access distros of Fuse, you unfortunately need to hack your ~/.m2/settings.xml file to reference our EA repo http://repo.fusesource.com/nexus/content/groups/ea/
e.g. here's how your ~/.m2/settings.xml could look
This step will be go away in next months GA release - sorry about that! :)
