The present invention relates to variant endoglucanases having improved thermoactivity, improved thermostability, and improved viscosity reduction activity over wild-type M. For instance, a registry federation can be stored in a set of one or more storage devices, the registry federation including multiple registries, each registry having one or more records. In embodiments enabling bidding for access to one or more out-of-network camera systems, a bid management system may receive a plurality of bids for accessing one or more camera systems, determine at least one winning bid and corresponding winning bidder from the plurality of bids, and provide access to the one or more camera systems to the winning bidder.
