There are maximum sizes, and I have not ever run into them. My systems 
have configurable telemetry streams built on top of CORBA Event 
Channels, typically with some header info and sequences of doubles or 
images. The images can be 128x128 or 256x256 doubles and can have 
several in a transfer packet. Past systems have sent even more in a 
packet. My point is that if you design for "reasonable sizes" of 
hundreds of kilobytes or less, then you will be unlikely to run into 
limitations. If you do run into a limitation then you can configure your 
system to work around it. You can search the omniORB and TAO mailing 
list archives to see discussions of configuring for large packet sizes.
