Progress is on a roll.  They acquired Mindreef, an SOA QA and validation company, two weeks ago.  Now they are acquiring IONA, a leader in CORBA technology for the last 15 years.  This move helps Sonic win customers looking to integrate their C++ based systems into the SOA world.  Progress now has Actional, Mindreef, and IONA.   Sonic has lost a huge amount of market share to IBM and Oracle, but these acquisitions strengthen their position in the market.
