I don't have any spectral files handy to test it, but my guess is that you can create a simple URL to pass to the first page, at least.
Take a look at the source for the page you reference. Look for the "input" elements, such as "sms". It has the options "smoothed" and "unsmoothed", so it's very much akin to keyword arguments.
The URL constructed from this web page will be turned into a request something like this:
http://smass.mit.edu/cgi-bin/busdemeoclass-cgi?spa=input& ;sfn=c:\\temp\\b.pro&lun=um&sms=unsmoothed&smv=1 .00&tax=ir&sls=sloped&slv=1&int=0
(You can see this if you visit the web page with HTML debugging turned on, and show the network traffic. I'm using IE 11, but I believe most modern browsers have this capability.)
This is a POST request that could be passed via an IDLnetURL object. It would be up to you to parse the result and possibly respond to any error messages or further prompts.
In the end, it's a simple matter of string parsing.
