Subject Re: off-topic request for suggestions

I think that I would opt for option 2. I think the chance that 
people would use both an ASP parser and PHP parser on the same file 
is a stretch. Seems that use of MIME type could control which 
parser gets it anyhow. I think that getting behind the momentum of 
ASP would have some benefits with editors, etc. as you mentioned.
