Indeed, as you say Matt, it's been quite an investment for us, as the major project for three techs for most of the past year, plus some outsourcing, so you do the maths... so we do feel we deserve a commercial return. I'd only add (a) that our prices are eminently reasonable and the quality excellent; and (b) that we do offer to let users have the fabric woven elsewhere, in return for a release fee for use of the service. We hope most people would consider this fair.
