One of the things you could do with these is to make a High Resistance transfer standard similar on configuration to these:
http://www.ietlabs.com/esi-sr1010-resistance-transfer-standard.htmlSelect sets of 5 resistors for parallel use so you end up with 10 or 12 10G resistors that match to better then 1%.
Many DVM's can measure up to 1G. This transfer standard can give you 9G and 100G of known values to 0.01%. All it needs is short term stability. The actual resistance values are not very important.
Also if you select resistors to give you 10 100G resistors within 1%, you can transfer 10G to 1000G. Not sure who needs it, but you can do it.
I am planning something like this with 100M resistors and with cheap reed relays to do the shorting and un-shorting so I can calibrate 100M and 1G ohms ranges of multimeters from the 1M range. Just have to make cards with small magnets glued on to short the relays I want for a particular type of transfer.
The only catch is if these resistors end up having a big voltage coefficient, then they are not much use for this.
