Anyone used Terracotta?

[Daniel Dyer]

Has anybody here used Terracotta for developing clustered applications?

Their recent switch to Open Source has got me looking at it again, and it
looks very impressive. However, everything I've read is from the
Terracotta people themselves. I was wondering if anybody has anything
good/bad/indifferent to say about it?

And for those who haven't seen it before:
