In the future...
It won't be long before GPS units are able to think for themselves and generate a GPS approach on the fly. You just give it the airfield and runway and it then plots an approach from your present position using the fairly rigid rules of PANS-OPS. All it needs is digital terrain elevation and obstacle data. Up pops the approach on your MFD, connect the autopilot, press the download button and the plan goes via datalink to the tower, all the controller has to do is watch the dot move along the line on his screen (without radar) 
A few years further on, all planes on approach talk to each other, 'know' each others approaches and factor that in.
Controller puts the kettle on..

I have just parted with £132 to the 'cost recovery agency' for a ferry permit.
If comes on nice stationery with the letterhead and a serial number and official stamp. Seems like a good way of raising revenue but it has no airworthiness function......

DIY GPS approaches are OK, up to a point, but in my Garmin I understand that there is some software that reconises an official approach or a coded overlay so that when changing from Enroute to Approach it alters the scaling for the CDI.
If you programme your own waypoints, the software won't pick up the change and you may have to fly the final part of the approach with, what is in effect, a too sensitive CDI.
Not a problem if you know about it and have 'good hands' but it could catch you out.
Better course of action is to badger, squirrell or rabbit on to the CAA thru' any official channel one can (AOPA, PPL/IR, etc)) to ex digitate
There are like-minded people in there, I've met some but they need the weight of pilot opinion to break the inertia.

There are several ways to use a GPS for a DIY IAP, with the OBS mode being perhaps the best way, but all require some prior due diligence with a terrain map before the flight. Personally, I would never fly a DIY IAP because FAR 91.175 makes them illegal in an N-reg
but if I was doing it, I would fly it under VMC beforehand. Unless the chosen MDH is something really generous like 1000ft but in that case it is not illegal in an N-reg because one is visual at/above the MOCA.
