What about using the HTML window? Could some code do this:
Make a custom EQ2MAP_HTML window that defaults to a url that will automatically submit a POI.
For example, most browsers will place
http:// on the front of whatever you type - our window would place
http://maps.eq2interface.com/submitpoibyloc= or whatever.
A button could be added to the EQ2MAP window that does the following:
1) Open the custom EQ2MAP_HTML window
2) Set the address bar of the window to equal your current /loc
3) Activate whatever the "Go" button is to submit
This would, in effect, submit the following url:
http://maps.eq2interface.com/submitpoibyloc=45,54,456 (pretend that the /loc is 45,54,456 obviously)
Now, the website would return a very simple page (one that would be able to display in the ingame browser window) that allows the user to then fill in the blanks such as POI name, etc.
Granted this is a bit of work for someone, but if one of you eq2interface gurus can give me an idea of how possible this is, I'll be happy to work on it.
I am all about making things easier for the everyday player - if this is something feasible, I'll do my best
Edit: argh, I can't make the website not add the url tag around those examples
