ESB consolidation - Progress buys Iona

I guess Iona was one of the first well known Irish software companies, and now it must be one of the last. It has succumbed to Progress Software for $106M. Paul Freemantle beat me to the news that Progress now owns or is a major committer for at least 4 different ESBs - Sonic, Artix, C24 and ActiveMQ/Camel/ServiceMix (plus Actional if you like) - hey, that's more than Oracle isn't it? (or maybe not...).
