What your program does: eg. get content from local disk or get content from a machine miles away, has nothing to do with the browser...as long as the web server displays output before timeout (about 90 secs) then all is fine. the only issue there is how is the webserver going to get the data from the remote machine (your home pc) Unless you have a static IP address or can inform your webserver every time your ip address changes, and your isp doesn't block access from internet to your pc, then you should be ok.
