We have been using a really rapid web application development environment
called DESL, which enables full website integration with mainframe or
midrange (IBM AS400) database systems. Because DESL allows fast builds it
isn't too budget hungry, so it might be the solution you are looking for.

DESL is compatible with most popular web servers such as IIS, Netscape and
O'Reilly's Website and supports Javascript, VBscript and Java.
Some of the major design principles underlying the product have been
inherited from the robust server environment of the AS400. For example
'Session Logs' which enable DESL to provide true user demographics and 'Hot
Swapping' which guarantees 24x7 availability of web applications.

There are two options for your non-member: Firstly, DESL could talk to an
AS400 directly using SQL or Stored Procedures via any ODBC driver (Netsoft,
IBM Client Access, StarSQL or ShowCase). The other technique is to use
server-side ActiveX,components to encapsulate business or data access
logic. These components could be written in any ActiveX aware programming
language such as Visual C++, Visual Basic, Java or Delphi.

DESL is developed by a company called Q4, and you can get downloads etc at

http://www.q4.com. Naturally, we'd be happy to talk to your non-member
about their requirements in more detail !
