Web Service Interface to PHPList

(I'll reply to your reply tomorrow, Michiel).

I have an external license management system that issues license keys, 
and I've written a PHP SOAP interface (that uses PEAR's SOAP module, 
rather than PHP 5's) to PHPList.  This allows my external system to talk 
to PHPList to add users (when they purchase a license), plus auto-update 
their email address when they tell me about an email address change and 
auto-subscribe people to a list when they buy a specific product.  I 
also use this to maintain beta user lists, and the beta system allows 
certain rights if someone is subscribed to the beta list (private list).
I currently have this in a separate directory so it can be .htaccess 
controlled and require SSL, but it wouldn't be hard to move this to a 
subdirectory of the PHPList tree to allow more general use.  I think it 
would probably require some customization by anyone to use, but if 
anyone's interested in this, I could contribute it and help someone else 
make it work more generally.
Anyone interested?  It currently supports the following interface:

+ <operation name="findByEmail">
+ <operation name="findByID">
+ <operation name="findByForeignKey">
+ <operation name="createUser">
+ <operation name="changeEmail">
+ <operation name="getAllLists">
+ <operation name="getSubscribedLists">
+ <operation name="getEditHistory">
+ <operation name="getMailingHistory">
+ <operation name="subscribeToList">

(This is copied from the wsdl output - the methods and other interface 
details didn't seem appropriate here)
It's certainly not full-featured, but allows external systems to do 
basic maintenance without having to directly access the table 
structure.  I've interfaced to this from both PHP and perl - it's pretty 
cool to see it work, but certainly not a "beginner" material.
Anyone interested in participating in flushing this out?
