comment Is there a way to split up my SSH Key using Shamir's Secret Sharing?
Shamir's Secret Sharing is defined with Lagrange's polynomials, precisely: there is a unique polynomial of degree at most t-1 which goes through t given points, and it is rebuilt as a linear combinations of Lagrange's polynomials. When the secret is shared, a random polynomial P of degree at most t-1 is generated, such that P(0) is the secret. Then user i receives share P(i). Any t shares are enough to rebuild P and recompute P(0).

comment In Tor, what stops the end server from following the breadcrumbs back to their origin?
Forward secrecy is about the impossibility of decrypting past traffic when, at a later date, the "permanent secrets" of one of the involved parties (SSL server) are compromised. It does not change things much with regards to anonymity: if the past traffic was recorded, then its provenance (previous node in the chain) is already known.
