Normally these things are a disposable asset, but wishing to find out how they work I took one apart.
There are 150 of these kegs available which are available as a whole lot NOT individually at an amazing price of £75.00 for the lot. Ive posted this in the Equipment Section as it will more than likely last the test of time and may prove a valuable resource in the future.
Basically having de-constructed the thing its a simple anti taper plastic thing (rather like a soda bottle top part but in reverse) and a screw on spear.
The biggest hurdle would be unscrewing the spear although this could be done simply with a home made spanner / socket with 4 cut outs on it (rather like the Halfords socket I made for my crusader kegs).
So in theory for the homebrew bunch of DIY enthusiast they could certainly be reused.
The only reason for taking the keg apart was to actually see what was happening inside.
Now before anyone asks about setting up a group buy....... I`m NOT
interested , to get this deal you will need to collect the 150 kegs as one lot from Norwich, I can only simply pass on the contact details of their owner , nothing more, BUT you will more than likely need to collect them this week.
If someone was to pick them up and sell them in multiples of 2 for £10 delivered I reckon they would make over £200 in profit (based on £6 post and packing). It would be a right ball-ache packing and sending them though so not sure it would be worth it.

my idea would have then been to pass them on "collection" first in a set of 4 to 5 kegs each member of the group only having say 30 kegs to move on...... 6 to 7 collections would have done it. The lucky owners paying say £25.00 to £37.50 for 5 kegs
