There's even an approach which /does/ allow \jobname to be
used without the need to get into catcodes and the difference
between an expandable token (\jobname) and a macro (\thisname).

Let the projects live in a directory "P".  Create sub-directories
of "P" called <whatever>, one for each possible value of \jobname.
Create one-line include files, one in each sub-directory,
called (e.g.,) "DocClass.tex".  Each should contain a single
line of the form

	\documentclass [<options>]{<class>}

where <options> and <class> are as required for that specific
value of \jobname.

Each main file in "P" will then start with the line

	\input \jobname/DocClass

and each will therefore \input as the very first record

	\documentclass [<options>]{<class>}

where both <options> and <class> are a function of the jobname.

Clear as mud ?! :-)
