+----------------------------------------------------------------------
+Memory allocation locality:
+
+Currently mallocs memory in a very haphazard manner. As such, most of
+the program ends up core-resident all the time just to follow all the
+stupid pointers around. . . .
+
+----------------------------------------------------------------------
+Input parser:
+
+The reader implemented in readfile.c could use improvement. Some sort
+of "data-driven" parser should be used so the big switch statements
+would have only one case for each data type instead of one case for
+every recognized option symbol. Then adding a new tag would involve
+only adding a new element to the data table describing known symbols.
+Hopefully, this would shrink the code a bit too. -gwr
+
+----------------------------------------------------------------------
+SLIP Initialization via BOOTP:
+
+In the function handle_request(), both in bootpd and bootpgw,
+we might want to add code like the following just before testing
+the client IP address field for zero. (bp->bp_ciaddr == 0)
+(David suggests we leave this out for now. -gwr)
+
+#if 1 /* XXX - Experimental */
+ /*
+ * SLIP initialization support.
+ *
+ * If this packet came from a SLIP driver that does
+ * automatic IP address initialization, then the socket
+ * will have the IP address and the packet will
+ * have zeros for both the IP and HW addresses.
+ *
+ * Thanks to David P. Maynard <dpm@depend.com>
+ * for explaining how this works. -gwr
+ */
+ if ((bp->bp_ciaddr.s_addr == 0) &&
+ (bp->bp_htype == 0))
+ {
+ /* Pretend the client knows its address. It will soon. */
+ bp->bp_ciaddr = recv_addr.sin_addr;
+ if (debug)
+ report(LOG_INFO, "fixed blank request from IP addr %s",
+ inet_ntoa(recv_addr.sin_addr));
+ }
+#endif

+DHCP Support:
+
+There is a set of patches from Jeanette Pauline Middelink
+<middelin@calvin.polyware.iaf.nl> to add DHCP support.
+
+Those patches will be integrated into the BOOTP release stream
+very soon, but if you can't wait, you can get them from:
+nimbus.anu.edu.au:/pub/tridge/samba/contributed/DHCP.patch
