Michael,

It might be interesting to take a look at what the US (and perhaps
others') National Virtual Observatory is doing. A different scale, of
course, and accessing data stored elsewhere, as opposed to TASS. But,
nevertheless, the US NVO is web-based and will be accessed by a lot
people.

Maybe, perhaps in the long run or not so distant future, TASS data
might be made accessible by the NVO, so your only problem would be
make the data acessible to them through their net requests. Then you
wouldn't have to worry about the web interface side of things. As an
additional plus, there'll be tools available to NVO users to model
data in general, and hence those of TASS in particular.

Cheers,

Mario
