How about ICE stability and performance.
Can I use ICE at Telecom platform.
I worry about stability and performance.
I have a passing interest in Ice :-)
I don't see why you couldn't use it for that application area. Have a look through this forum. You'll find that few bugs are reported, that those that are reported are typically minor, and that a fix is usually available within hours.
Defect count in Ice is low, most likely lower than for other middleware products.
