CGI's in Plugins

I am new to WP. I have a gigantic library of code that is all CGI stuff that I would like to wrap and repurpose as a WP plugin.

The Plugin architecture is straight forward. I can write wrappers and have plugins for my/ my companies own use work just fine.

But I am unfamiliar with various hosting situation used by the typical WP user.

My question is this: Does the typical host allow CGI’s to be run from the WP plugins directory?

If I put the CGI in the “package” that contains the rest of the plugin: will the server allow it to execute.
