Hi, first of, im not sure this is within the correct section. If not please do tell =)

So my problem. I'v created a custom section that has its own node structure. The nodes are not created within umbracos db table for nodes, they are in there own tables. Now I need to create a smooth jQuery menu that is basicly the same as the on used in my custom section. Im thinking of using a webservice to return all the nodes. Since the custom section shows different "products" for different customers (multiple sites).

If i use a webservice for this, where do i place it so that is has the same loaction for all different sites?

The webservice will be called by a .net usercontrol that will be added as a macro.

Is this a good solution? Or should I go in another direction? Only use .net usercontrlols?

Any feedback is very much appreciate!
