In addition to the black market ideas of special Fixer stores, what about a Fixer-Only Black Market chat channel?
Consider the description of the class: Fixers can get things that are hard to get and they can get them quicker than anyone...what better place to get them than from another Fixer?
Fixer A: Hey, I have an engi looking for the ____ nano. Anyone have one handy?
Fixer B: Have two..I'll let you have one for XXXX credits or trade you for a QL 50 Nova. I have some slobbering soldier offering me some decent cash.
Fixer A: Nope, no Nova..I'll take the nano though. And mark up the price 20% when i sell it to him
Fixer B: Cool, I'll meet you at Reet Retreat.
Fixer C: Hey, I have a QL 50 Nova. You wouldn't happen to have spare Mausser to trade for it? Mine is getting old.
Fixer B: Sure, just meet me us at Reet and we'll do a deal.
ETC ETC ETC
You get the idea. While on the surface this might be just another shopping channel, it could be a lot more. Information is as valuable as items sometimes, and a Fixer wide channel, regardless of affiliation, would be realistic. Fixers on the whole have more loyalty to themselves than any group they belong to I think. Or they should if they want to make the cash. Criminals talk to criminals.
At the least Neutral Fixers should be able to communicate with both Clan and Omni Fixers, then Clan Fixers could pay to get info about Omni plans they could sell to Clan guilds/leadership and vice versa, with the Neutrals finally having some USE for a change.
In the RP sense, this also opens up untapped potential of characterization...is your Fixer a guy all about getting the loot and fencing it quick? Is he a Robin Hood type that uses his own wealth to get items and then gift them to the needy? Or maybe she's a loyal Clanner that uses her underworld contacts to find out what diabolical plans those OTs are hatching this time.
Not having a clue about programming, I have no idea about the technical side of implementing this, but if they can already do channels for other specificities, this shouldn't be too hard.
And it may work as a bone FC can throw us until the big fixes show up.
