I'm aware of that Lyn, however if they can render an NPC logo on ships, I can't imagine it will be to hard to something like this...
Update logo-creation engine to be easier to code, if needed, and generate the logo's in a format compatible with the ship's skin -> Render an area of a ship, likely where the faction emblems are now, to display the pre-rendered corporate logo -> enact logo-changes only during Down-time to cut back on any lag issues and quell server loads -> possibly allow Alliance emblems to over-rule corp ones if able. This one will likely require a severe change to the alliance-emblem creation rules and means, but it might be possible.
That last one is the least likely, tbh. For my part, corp-logos on ships would be hella-nice. Asking corps to fly only one faction's ships is hard because it denies allot of skill-point use and brings tactical limitations, but a unifying corp-logo will still help on that 'unified color' feel, regardless of the origin on the ships flown. Still, I consider it unlikely to happen any time soon and I don't expect or even think it might happen, but it would be nice to see, regardless.
For the moment however flying militia with T1 ships is already awesome.
