Hi Mike,
Insight is clearly supported - no problem there. ABC and Legacy examples are included.
Secwin 4 includes a lot of support for the Web Server, but it's still waiting the completion of the EIP stuff to be 100% ready. Scheduled for 4.31.
SelfService, Message Box and WinEvent are all good to have in the server program (although of course your users won't see these.)
It's the same for Fm2 / Fm3. It works fine in the program, although the user doesn't see anything.
xFiles is a recent "helpmate". With version 4.30 I've included some SOAP server examples which use xFiles. Xfiles also has some example of making a SOAP client.
Reports made with RightReports can be "run" through the web interface (example still to be done) but you can't (currently) edit reports via the web browser.
I've probably forgotten some but these are all worthy of consideration.
Cheers
Bruce
