Their IT dept doesn't allow 'unapproved' installs of executables (which 
may exclude browser plugins, but we'll see)! And the approval process 
is, well, difficult. I think you have to know someone. As I [very 
limited] understanding of it, they use mostly COTS software (at least in 
the area where my client has customers). Actually I may have heard the 
COTS part from someone on this list a few months ago.

True.

I suspect ultimately we'll have to go with an irev-enabled site to 
deliver the goods, which won't be a bad thing at all - we're just trying 
to avoid the refactoring of existing desktop app functionality at that 
extreme.

Thanks Richard.
