We've traded a few messages in these forums; I ran a derivatives book (including all types of "exotics") and as usual, the increasing complexity of the product = more vig for the house. Some are 'bet' options others are barriers, some pay out if a target is hit, others if it isn't. One way we are effected by the presence of these options is when an exotic deriv book needs to rebalance a greek metric...more on that a little later.
These options have ridiculous (think discontinuous) deltas, insane gamma and exposures that plain vanilla options just don't have. Sell one type of exotic and you're long vega; as time approaches expiry in another, you can be so short gamma that 1000 long atm 1 week straddles won't cover it (technically).
One thing that you mentioned is really important - all these exotics are dependent upon the flies, skews and vol of vol. Watch the 25 delta flies; exotics traders will use them to adjust certain exposures...
My "handle" is one of type of exposure - dvegadvol - change in vega position for a change in the level of volatility! There's also dvegadspot - change in vega for a change in spot price - directly relates to the fly and strangle markets.
If you've got any questions about exotics, let me know.
