	I see. Thanks for the information.

	*nod*. I can understand the move to 1.4.
	
	wrt your last question, I have to ask first - is there a proposed
	timeline for the 1.4 releases at all ? How soon will it be before we
	get our hands on a (beta?) version ?

	How much effort do you think it would it take to get 1.3.0/1 up to
	speed ?

	Cheers,

	Marcus
