An annoyingly broad answer, but: broadcast an opportunity in which you provide vetoed access to the server/instance holding the data (eg, with standard user accounts, private home directories and the data located read-only in a dir off of /). Would create a small storm of overhead ("please install ..." ad nauseum), but provide interesting opportunities for open-ended creativity.

Also, while unusual, you could potentially extract value by lightly imposing requests ;) on others to (where viable/a good fit) at least have a go at helping you with problem-solving/busywork-type steps in the research you're doing (however experimental/uncertain). Since everyone would be looking at the same dataset, this may bring interesting/unexpected ideas to the table (and maybe even shed light on potential opportunities for collaboration down the road). For individuals who are reasonably independent and self-directed but have no experience working with huge amounts of data, this would also provide a cool chance to play around in a real-world-scale environment without the failure risks attached to eg fulfilling^Wfiguring out business requirements etc.

(Now I'm reminded of https://tilde.club/, which operates a shared Linux box a (very) large bunch of people have collective access to. It's a stab in the dark (ie, the one reference I'm aware of), but maybe the admins there would have interesting insight about managing shared access Linux boxes.)
