As long as you dont disconnect the tap and applied some sanitation procedure to the inital tapping then you can consider the keg and beerline feed up to and including the Tap All part of the same enclosed system. And the only area you need concern yourself with is the tap spout which will benefit from a rinse out between sessions.
The connect to keg taps are imho as worthwhile as a chocolate teapot loss of condition is inevitable when you maintain a keg at the low pressures needed to pour without a catastrophic loss of all co2 contained as condition.
your much better off imho modding your party tap to include a length of upto 5-6ft of the thin 3/16" micro line. this not only coils with a much tighter radius so is way neater it also has the effect of reducing the keg pressure along its length so that at the tap the pressure difference isnt high enough to cause a foam out.
so to sum up
1) mod the tap to include a length of pressure reducing 3/16" micro line to balance off your keg pressure as a rough rule of thumb 1 foot length of micro line can drop 1-2psi of keg pressure. The goal being no more than 1 1-2psi difference in pressure at the tap release as anything higher can stimulate the foam out
you can ebay modded party taps even..
2) maintain good sanitation procedures when tapping a keg (wash post, tap, and tube etc, before rinsing and sanitising (starsan is a godsend in such situations)
then once tapped leave the tap in place and you can consider the tap and its beerline feed a simple extension of your keg and forget any worries about it.
btw due to the pressure reducing quality of the micro line beer close to the tap will loose its condition in the line and there will be lots of visible gas bubbles, NOT A PROBLEM.. the beer contained in the beerline is a drop in the bottom of the glass, all it means is the start of each session the tap will cough up 1/4 - 1/3 of a pint of foam which if left to sellte would be a couple of mm depth in the glass which you can simply discard before continuing to pour a well conditioned pint
Well thats my take

ist update for months n months..
Fermnting: not a lot..
Conditioning: nowt
Maturing: Challenger smash, and a kit lager
Drinking: dry one minikeg left in the store
Coming Soon Lots planned for the near future nowt for the immediate
