I have changed my setup a little, trying to focus more on getting to raid level to participate in that (Not to multi in it though, not yet at least)

Anyway, I am currently only dual-boxing, and changed my characters around a little. I dropped the cleric and one of the druids for the time being.

My current lineup is my main Elesar (35 BloodMage) followed around by Elthis (23 Druid).

Elthis is leveling extremely well, with the aid of Elesar, my brother Nieger (23 Sorcerer) and my friend Zheyla (25 Disciple). But once I get in range to have Elesar actually in-group with the rest, it will be on then (Vanguard has a 6 level grouping cap if you want to gain exp)

Current setup consists of two systems, both running KeyClone with whitelists for numpad, the number keys, and the f1-f6 keys, along with "f" for assisting and spacebar for clearing obstacles.

I have considered getting an X-Keys control, but cannot decide what all I want (either Pro or Desktop), or how I would implement it yet, just have to plan a bit more.

I am looking into upgrading my network to Gigabit for improvements with overall latency (I run a fileserver for a WAN, so my bandwidth gets a bit of use) and will be getting a better internet package once this contract is up.

As far as your problem Azorel, KeyClone sends key input at a low level, so theoretically, you could send exactly what you wanted to the second computer, and as long as you don't have anything bound to those keys on the main, then you would be set. But, I'm not all that familiar with the G15 or sending anything other than standard key-presses with KeyClone, I don't even have any modifier keys(Shift, Alt, etc.) that I broadcast with my current layout.
