Nice. I’m just about to create of PoC with Strophe that should use some of the functions of 325 :-) It is of course up to you what kind of license you want to publish your code with. Strophe itself is MIT licensed. If you are ok with everybody using and or changing the code for whatever they want the MIT license is great. From the Wiki: https://en.wikipedia.org/wiki/MIT_License The MIT/X11 license adds the following clause: "Except as contained in this notice, the name(s) of the above copyright holders shall not be used in advertising or otherwise to promote the sale, use or other dealings in this Software without prior written authorization.” I’ve used both the MIT and BSD 3-Clause License. These licenses are similar except that the BSD license contains a notice prohibiting the use of the name of the copyright holder in promotion (just like the MIT/X11 license above).
