[casual_games] Prior knowledge or links on licensing fees?

[Morbus Iff]

G'day. I don't know the verbiage for what I'm asking.

Given a unique casual game engine/framework, and a desire to license the 
game engine/framework to other sites for their use, some questions:

  * the source is not compilable, so releasing it for use on someone
    else's server (like a Flash app) is not possible. How horrific
    is it to force a licensee to use our own servers (either through
    yourcompany.ourcompany.com or via ourengine.yourcompany.com)?
    The licensee would still have control over appearance and
    community functions, but there'd be little integration with
    their own site and technology (save for visual aspects).

  * is licensing a one-time fee or a duration based timeframe?

  * how are version upgrades, or feature enhancements, to the
    engine handled? free upgrades for X months, and $Y after?

  * what type of support contracts to the engine do people expect?
    do they expect the game to work out of the box (which, in
    this case, is "odd" because the /content/ of the game is
    a licensee-customizable thing) or do they expect to tweak
    the engine and rulesets and code to their own needs? are
    there different type of conditions for each contract?
    how does this affect the cost of the license?

  * what would you expect to pay for a license
    and what would you expect from it?

I realize these are hopelessly wide-open questions that require lots of 
further clarification, so if there's prior art or documentation on this, 
I'd love to be link-bombarded. Licensing is simply not an area I've 
dealt with before.
