CIFS component to wrap around given CRUD web services

I'm pretty sure this is a very particular request, and am slightly proud of it :-)

I am looking for a CIFS (Common Internet File System) adapter/layer/wrapper around an existing set of web services, that takes an incoming CIFS request and translates it to some calls to these web services.

Explanation:

Say we have a document management system that provides nice web services to "crudl" (create/read/update/delete/list) files and directories.

Say that this document management system does not support the CIFS protocol, which is the protocol that enables users to open a directory from that system in Windows Explorer as if it was a local folder.

Say that our users still want this feature. Wouldn't it be nice if we could simply install some kind of adapter component which implements the CIFS protocol suite and, behind the scenes, calls to the given web services to perform the CRUD operations? Of course it would need to be configured such that it knows where the services are and how to use them.

Do you know whether such a component exists? I didn't find any on google.

Or, if it does not ex开发者_StackOverflowist, would it be difficult to implement one on my own (in C#, e.g.), or to take some existing CIFS implementation code and modify it?
