Tzipi,

Your application would not be supported out of the box.  You could use
mapserver for the mapping, but when you want to process the profile request
that would have to be done via some other mechanism.  In theory you could
write a python cgi that used GDAL to sample along the profile line, and
then drew some sort of graph.  But your application will take substantial
customization and effort on MapServer.

Of course, it may be that not many other mapservers would support this
easily out of the box either.
