c++ - Compiling on-demand executables -

gotomeeting's gotomeeting.com/join has interesting behavior - when visit meeting url straight you're required download new exe binary file which, when executed, has meeting id already integrated , auto-launch programme without needing input meeting id.

my first thought incorporated metadata of executable, closer inspection leads me believe these exes compiled meeting id.

so here few questions:

are building/compiling on fly? if so, isn't there massive overhead implementing this? this has massive security risk, right?

so assuming silly plenty effort - there safe way issuing make, etc. web-based framework? gut tells me there isn't.

i've read next questions tell me kind of question typically met much ire:

fast on-demand c++ compilation

silverlight on-demand compilation/build

i don't see why issuing make within web-based framework must insecure. may, may not. slow , result in unacceptable delays.

the more sensible approach, in opinion, have executable compiled, "blob" of reserved info in resulting file substitute actual info want , sign resulting file.

this faster compiling , easier implement boot!
