Yes, several.
ENLAN-DFS from Interworks provides peer to peer networking and Distributed File System over SANA II compatible hardware.
Envoy from IAM provides peer to peer networking for Amigas that is tied very close to the operating system. It too is SANA II compatible.
Resource Management Force has a zorro II card called QuickNet which uses thin ethernet, and special Amiga to Amiga software.
ALAN-FS is a peer-to-peer network package that allows full transparent file-sharing, device sharing over ethernet. It requires WB2.0 and the Commodore AS225 package. It is available from GfxBase, Inc , or Canadian Prototype Replicas . NOTE: Current Product status unknown. FEEDBACK appreciated.
Dnet --- Dnet has client/server software for both Amiga-Amiga and Amiga-UNIX networking over a serial line. Among other things Dnet supports shells, file transfer, IRC, and something like NFS. Dnet is available on Aminet .
PARnet/PARbench --- PARbench is a workbench installable version of PARnet which allows two Amigas to be networked using a parallel port and cable. It is basically file sharing similar to NFS, but Amiga only. PARbench greatly simplifies installing and using PARnet.
