I've set up some on documentation around the new transaction functionality:

- recovery, linked from the main documentation page: http://community.jboss.org/docs/DOC-16646?uniqueTitle=false

- Synchronization: http://community.jboss.org/wiki/InfinispanTransactions#Enlisting_Synchronization

I also plan to :

- add a doc describing how to set up recovery with JBossTM and Infinispan - ISPN-1080

- add some performance numbers on the overhead of a) using tx b) using tx with sync c) using tx with recovery

- add a blog entry around this stuff.

Any feedback appreciated. 

Cheers,

Mircea
