We cable tie them to the cab itself, but these velcro buttons sound much better,
We also have an ftp site for techs, dirt cheap to setup (easy if you happen to be a hosting company or ISP) alternatively a company I use personally is really good (not sure if this is allowed but I'm sure the mods will correct me if i'm wrong!)
www.ovh.co.uk (they are all over the world), its about £28 a year for a domain and hosting, you can obviously go higher but as a basic start its not bad.
Sorry mods if thats not allowed.
