Your solution is elegant, AIiCE, because it be much easier ta travel to a place where your own domain is strong.
One of th' advantages of th' HELRIDE system is in th' virtual space within. There you could store stuff before transportin' it, includin' your personality, a probe if need be, ect.
Also, th' meta-fiber optic link would be maintained at all times, so you could even exist as an electronic avatar in your own world, borrowin' laws of physics from th' Immortal Facets in th' location immediately around th' connection point. Th' optics could transport anythin' that can be conveyed as information (though of course you'd see a strict limit on locality - ie reach - that you could get around by possessing some existing electronic).
Then, with multiple nodules, you could transmit information at a fairly high capacity through ta HELRIDE central an' out again wherever you pick. Th' transfer would be truly instantaneous in every meaningful way ta any being limited ta 3 spatial dimensions.
At your option, it might be wise ta put some pretty heavy duty firewalls in HELRIDE central. Eitr could spawn a thousand AI's outta this thing if we're not careful. But don't worry, I've got th' resources ta build such a firewall.
