Very interesting "Agamer" - are you doing an 'Elite' style game? As that is exactly what I have been faffing around with today. After seeing 'ArxSpace' at Blitzcon, I thought 'How hard can it be to do an Elite game?'. The original game was done in a poxy 28k (If I remember correctly, coz it was designed to fit within the BBC's 32K) of code. I reckon it is worth a shot.
