[Q] In-Browser technology

[Vladik]

Hello,
Sorry for cross-posting, but
my question is really to the people on the news groups
who know about Eiffel, Python and Perl.

Basically,
We are to develop a web client (a program that
can be ran witting a web browser) for our otherwise n-tier
cross-platform system, our research department gave the
recommendation and actually a prototype of the client
in MS ASP (active server pages) and, I think but not
sure, blended with Visual Basic. Talk about bias...
But this means that it can only run in MS IE and not
in Netscape, also it limits the number of platforms not only
for the client on which web browser runs, but also for
the web server (MS platforms only, because web server with
active pages can only run there)
There is some talk about Java, but our web client
will also be ran via Serial links (not T1 connections)
on relatively inexpensive systems -- therefore Java is
something to look into but it may be slow.
So I am set on a quest to find something
that
a) can be executed within IE or Netscape,
b) be faster and overall more resource friendly then JavaScript technology
c) supports OO programming
d) does not depend on the platform on which web server is running.( if the
web server is running NT or UNIX (sun, linux)

I have found one thing that almost satisfies the requirements:
it is based on Oberon-2 programming language and so far sounds
VERY promising.
  The reason why I am still looking is because
there are more books and internet support for Python,Perl and Eiffel
then for Oberon (this will be a factor when presenting the proposal
to the management).  The other problem is that there is plugin
for this technology available for NT and Mac platforms (for both
IE and Netscape) and is not available for UNIX platforms (which means that a
web browser can not be ran on UNIX). There is source code,
though.

So, finally, my question is is there a technology
I am looking for available for either Perl or Eiffel or Python

Since I am cross-posting, I would appreciate a reply
by mail as well.

Thanks in advance,
Vladislav
