Would be nice to see Phalanger as a NuGet package to get an installation-free Phalanger (no GAC, no machine.config, preconfigured web.config) like detailed in this article:
http://www.php-compiler.net/blog/2011/installation-free-phalanger-web.
Other dependencies, like the mng-Files or the PhpNetMySql could then be added as supplemental packages.
I think that would increase the interest on this wonderful project massively, because to get in touch with Phalanger you have to pass some hurdles to get it running.
Keep up the good work!
