Sad to hear IBM is requiring whole suite upgrades just to support Juno :(
About JBoss Tools, you can still use that in Eclipse 3.7 - the only problem (and I understand it is annoying problem) is the missing EAP 6.1 support.
The hack would need to make EAP 6.1 look like an EAP 6.0 .... i'll see if I can find a way :)
