Sure thing
I'm already done updating the widget (wow, using the XML feed simplified things a lot compared to the old SOAP technique), just need that player ID...
If we know who's online (courtesy of HeroStats or TNT) that'd be useful info in the feed, too... maybe a top-level element like this with all of your Friends in it:
<friends>
<friend id="944" player="Ex-calibur">
<online>true</online><!-- or false... if true, we have: -->
<char_id>92448</char_id>
<name>Operative Rache</name>
<server_name>Infinity</server_name>
</friend>
<friend id="1" name="Maverick X">
<online>false</online>
</friend>
</friends>
If we're not implementing a Friends feature for CIT, you can ignore this for now. ;-)
